Need Advice: used 5D or New 7D

I'm here thinking of buying a 5d as I want to move to a FF DSLR. Cant afford the new 5d III or the 6d. So looking at an used 5d or a new 7D. I currently have a 40d and a 1d Mk II (which I absolutely love for the images it produces).

I am primarily looking at landscapes and people shots with my new camera. And occasionally use it for bird shots / wildlife. Is there a clear winner here?
